I have a question about hadgen cycle?

Question

I have bottle of cycle that was left open slighty oppened, do you think the bottle needs to be completely closed to save the good bacteria? Also can i put a goldfish pellet into the bottle to feed the bacteria for ammonia?

Answer 1

Unless the bottle was refrigerated, there won't be any live bacteria whether it was open or not.  For nitrifying bacteria to experience a period of dormancy, they need temperatures between 32* and 39*F.  Without oxygen and ammonia, the bacteria will quickly die, otherwise.

Answer 2

That stuff is useless.  Unless you buy refrigerated Bio-spira you might as well buy a bottle of water.  Bacteria can't live in a bottle like that for any length of time.  It's just a rip off.
